GUARD FOR WATER-GLASSES.

Specification of Letters Patent.

Patented June 29, 1915 Application filed March a, 1915. Serial No. 11,636.

T all whom it may concern:

Be it known that I, Gnonon W. AMns, citizen of the United States, resident of Staples, county of Todd, State of Minne sota, have invented certain new and useful Improvements in Guards for Water-Glasses, of which the following is a specification.

The object of my invention is to simplify and improve the guard shown and described in Letters Patent of the United States issued to me September 22, 1914, N 0. 1,111,518.

My invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification, Figure l is a side elevation of a guard for water glasses embodying my invention, Fig. 2 is a sectional view of the same, Fig. 3 is a transverse sectional view, on the line w00 of Fig. 1, Fig. 4 is a similar view on the line y-y of Fig. 2.

In the drawing, 2 and 3 represent the valves tapped into the boiler head in the usual way, and between these valves is a water glass of the usual type, indicated in Fig. l by dotted lines. It is customary to provide a guard or shield around this glass to prevent the engineer or fireman from in jury in case of breakage or being scalded by hot water from the boiler.

A device of this kind to be of any commercial value must be of simple construction and capable of longitudinal adjustment to adapt it for water glasses of varying length. With this end in view I provide two sheet metal sections 4 and 5, U-shaped substantially in cross section, each having front and side panels with their "abutting ends adapted to lap by one another and capable of sliding longitudinally to adapt the guard for different lengths of the water glass. The outer ends of these sections are provided with wings 6 and 7, which are folded inwardly and provided with recesses 8 to receive the portions of the valves 2 and 3 in which the ends of the water glass are mounted. The side panels of the sections are also provided with lugs 9 and 10 arranged in pairs and through these lugs rods 11 pass for clamping the sections securely together on the valves. The side panels have longitudinal openings 12 therein normally covered by glass plates 13 and for holding these plates in position I prefer to bend the longitudinaledges of the panels, as shown plainly in Fig. 3, inwardly to form flanges 14, said flanges terminating in outwardly bent portions 15 which cooperate with the flanges and the wall of the panel to form vertical guides for the inner edgesof the glass plates. The front panels of the sections are provided with plates 16 having inwardly turned loops 17 spaced from the side panels to form vertical guides for the outer edges of the glass plates. These loops and the flanges formed at the inner edges of the panels add very little to the cost of the guard and at the same time are thoroughly eflicient for the purpose of holding the plates in position. The glass plates of the two sections are mounted to slide by one another to allow them to accommodate themselves to the adjustment of the guard.

The plates 13 are preferably made of a series of sections to adapt them for varying lengths of the guard, as described in my former patent, above referred to.

In various ways the details of construction herein shown and described may be modified and still be within the scope of my invention.

I claim as my invention:

1. The combination, and valve therefor, of between said valves, said posed of sections mounted wise upon one another and each section being composed of front and side panels, said side panels having openings therein and transparent plates for closing said openings, said side panels having their inner longitudinal edges bent inwardly to form vertical guides for the inner edges. of said transparent plates, having plates secured thereon and cooperating with the outer portions of said side panels to form outer guides for said transparent plates.

2. The combination, with a water glass and valves therefor, of a guard interposed between said valves and composed of telescoping sections having side panels and longitudinal openings therein, transparent plates for closing said openings, the inner edges of said panels being inwardly and backwardly turned to form vertical guides for the inner edges of said transparent plates, and the outer portion of said guard sections having plates secured thereto and a guard interposed guard being comto telescope endand said front panels with a water glass cooperating With said side panelsto form Copies of this patent may be obtained for five cents each, by addressing the guard sections having plates the outer portions of said secured thereto and cooperating with said side panels to form Vertical guides for the outer edges 1 ofsaid transparent plates. 7

In Witness whereof, I have hereuntoset my hand this 20th day of February 1915.
